Abstract: By constructing packaging or cushioning components with a cellulose-fiber foam and uniquely blending relatively longer fibers serving as mechanical structure with refined chemical fibers serving as a bonding mechanism for the relatively longer fibers together, a lower density, energy absorbing, and resilient cellulose-fiber foam is disclosed. Some cellulose-fiber foam components additional do not require stand-alone foaming agent or surfactant.
